To all whom 'it may concern:

Be it known that I, ELIAS R. WIENER, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and

lState of New York, have invented certain Reference is to be had to the accompanyinv drawing in which igure 1 is an elevation with parts in section showing my improved lamp as an inf verted light; Fig. 2 is 'a plan view thereof partly in section and Fig. 3 is a detail seetional view on the line 3 3 of- Fi f. 2.

A is the burner tube to the ree end otl which is attached the usual mantle B. The said mantle B is carried by the usual ring B',

which in the present case is supplied with iingers or lugs B2.. These lugs B`2 are adapted to engage a support B:s which is removably secured to the burner tube A. The support Ba is provided with arms B4 having open slots into which the lugs B2 are adapted to enter, the :bent over portions of said lugs BX tl'1us}suporting the mantle in proper position 'the burner tube A. It is to be understool riat the lugs B2 of the ring B iirst engage i ,e support B3 with the bent over portions pl'ithe lugs B2 in the spaces between. the arms Naalter which the ring B is then given a partial/"turn so that the lugs B2- enter the open slots inthe manner of' a bayonet joint. The burner tube A is in communication with a mixing chamber (l provided wit h air inlets l). A shutter E provided with openings E is arranged to rotate about the outside of said mixing chamber for the purose of regulating the amount of air lo be admitted to the mixing chamber (l. 'lhis reguA lation of' the air is accomplishml by turning 'the shutter E so that the air inlets are moreor less covered. thereby, the maximum amount of air being admitted to the mixing'chamber when the openings llare in porl'eet. registry' With the air inlets l). 'l`he mixingr chamber C is al ached by mea-ns of s ,re\\-ll|r wnls lo the support F which in tum. is screwed on l he customary gas fixture at F.: To regulate the amount of gas which enters the mixing chamber, the support F is provided with a needle valve G adapted to engage the seat G in a portion of the support F which extends into the mixing chamber. The needle valve is operated by turningA the knob or handle G2 and is secured in any position b means of the lock nut G3. By thus provi( ing for the regulation off'the air and gas which enters the said mixing chamber C before it reaches the burner tube A, the most efiicient mixture is secured, to give the best illumination, without any undue waste of gas.

In connecting my lamp with the usual gas iixture, which I have not deemed it necessary to show, the support F is iirst screwed on said iixture, after which the mixing chamber C is screwed on said support at lC. In many cases the extent of the screw threads will vary so that when the lamp has been attached tothe support F in the manner just described, the burner tube A with the mantle att-ached thereto will be found to stand at an angle. To overcome this objection I provide a screw-threaded collar H which is in screwthreaded engagement with the support F as shown in Figs. 1' and 2, so that when the lamp is screwed on said support a sufficient distance to hold it (in the present illustration, with the burner extending downwardly) the collar I-I is then screwed up tight against the mixing chamber C, thus securely holding the lamp in position. If it is desired to use the lam p as an upright lamp', or in other words in the reverse position from that shown inthe drawings, this collar H is loosened and the lamp turned sothat the burner tube extends upward, after which the collar ll is again screwed up against the mixin chamber (l. 'lhe lamp is thus securely hel in position for use as an upright lamp. To

prevent the mantle from being dislocated by this change in position of' the burnertube, in case the mantle connection with said tube is a. loose one, the tube A is screw-threaded a part ol' its distance as shown at A to accommodate a nut I. This nut I is adapted to be ,screwed up against the mantle ring and thus cured to the burner tube by means of rivets M and is provided With two arms M2 which are secured to the ring K byrivets or screws Maj and form a yoke over the burner tube A. To steady the ring K and( prevent itl'roni sagging, the member M has an additional :nni M4 secured to the ring K at 'a point substantially o posite to the point where the arms M2 are astened as at-Mr. This construction results in a very rigid support 'for the globe, which support is also easily attached in position.'v i

. Various modifications may be made without departing from the nature of my invention as defined in the claims.

I claim:

1.A A11 incandescent gas lamp capable of being adjusted either to an upright or an ini verted position, means For securing said lamp 1 in either position, and means-for retaining f the mantle in proper loeationin either position of the lamp.

2. In' an incandescent gas lamp, a burner l signed my tube, a mantle supported adjacent 'tthe free end of said burner tube, a mixing cham- 25 v enters said mixing chamber, and. means for regulating the amount of gas which enters .said mixing eliani'ber, said gas regulating 30 means being in close proximity to the air regulating means.

3. An incandescent gas lamp capable ol'.

being adjusted either to an upright or an in'- l 'vcrted position, a lock-nut for retainin sai lamp in either position and another loc -rt lor securing the mantle 1n proper location in i either position ol the la1np.

1n testimony whereof, l have hereunto name 1n the presence of tivo s1ib- 40 scribing witnesses.
